The U.S. housing market continues to churn out positive year-over-year sales numbers, but some markers of hesitation are worth watching. Some sellers hesitate to list their homes because they are not sure that they will find an attractive replacement for their own fast-selling home. Many young consumers, saddled with student loan debt and having transient tendencies, hesitate to commit to a home purchase longer than previous generations. Nevertheless, home starts are on the rise, and the market remains strong during the busiest weeks of the year.
